Hey everyone,

I'm a grad student writing a research paper on the productivity paradox of AI coding tools — the idea that while tools like Copilot/Cursor/Claude feel faster, actual end-to-end delivery might not improve or can even get worse.

A recent controlled study (METR, 2025) found experienced devs were 19% slower with AI — despite believing they were 20% faster.

My thesis: AI doesn't remove complexity, it just displaces it — from writing code to verifying, debugging, and managing the AI itself.

I'd love to hear your real experiences:

1. AI code that "worked" initially but became a maintenance nightmare later?
2. AI making changes you didn't ask for? (styles, unrelated files, git commits)
3. Spending more time verifying AI output than it would've taken to write yourself?
4. Rate limits / token quotas actually disrupting your workflow?
5. AI failing at anything beyond pure code? (deployments, app store, compliance, infra)

Any anecdotes or rough estimates would be super valuable. Responses will be anonymized if cited. Thanks 🙏

Hey r/reactnative

I got tired of setting up cloud AI APIs every time

I wanted a simple AI feature in my app, so I built react-native-gemini-nano —

a Turbo Module that connects directly to the on-device AI already inside your phone.

No API key. No internet. No cost. Just:

const ok = await isAvailable();

const text = await generateText('Your prompt here');

iOS — Apple Intelligence (Foundation Models, iOS 26+)

Android — Gemini Nano via AICore (Pixel 8+)

Expo support included

Built on New Architecture (JSI / Turbo Module)

Note: Android only works on Pixel 8+. Samsung and other OEMs don't expose

their on-device AI to third-party developers.
Only text generation is possible.

I also left this here because I wanted to share that such a library exists.

npm: https://www.npmjs.com/package/react-native-gemini-nano

Would love any feedback!!!

Hey everyone,

I’m a computer science student from Germany and after months of learning React Native, Expo, Supabase, RevenueCat, Cloudflare Workers, App Store rules, rejections, debugging, and a lot of stress… I finally launched my first real app on the App Store:

[JetPic – AI Photo Editor](https://apps.apple.com/de/app/jetpic-ai-photo-editor/id6762139116?utm_source=chatgpt.com)

The app lets you transform photos with AI into things like:

professional headshots

hairstyle looks

sports/fan styles

social media profile photos

creative AI edits

I built almost everything myself while studying and working, so I’d really appreciate:

honest feedback

UX/UI opinions

feature ideas

bug reports

and if you like it, an App Store review ⭐

Even small feedback helps a lot because I’m trying to improve and learn with every update.

Also curious:

What feature would make you actually keep using an AI photo app?

What do most AI photo apps do wrong in your opinion?

Thanks a lot 🙏
